  1. Description of the pharmacokinetic(PK) profile for in terms of: observed maximum plasma concentration (Cmax), time to reach maximum plasma concentration (tmax), terminal rate constant (λz), terminal half-life (t½ z).

    Measured: Sample taken predose, 1, 3, 5, 7, 9, 13, 18, 24, 36, 48, 72, 96, 144, 216 hours postdose

  2. Description of the pharmacokinetic(PK) profile for in terms of: area under the plasma concentration-time curve from time zero to 24 hours after dosing (AUC(0-24)), from time zero to the time of last quantifiable concentration (AUC(0 last))

    Measured: Sample taken predose, 1, 3, 5, 7, 9, 13, 18, 24, 36, 48, 72, 96, 144, 216 hours postdose

  3. Description of the pharmacokinetic(PK) profile for in terms of from time zero extrapolated to infinity (AUC), apparent clearance for parent drug estimated as dose divided by AUC (CL/F; AZD4721 only)

    Measured: Sample taken predose, 1, 3, 5, 7, 9, 13, 18, 24, 36, 48, 72, 96, 144, 216 hours postdose

  4. Description of the pharmacokinetic(PK) profile in terms of apparent volume of distribution during terminal phase (Vz/F; AZD4721 only), mean residence time (MRT, AZD4721 only), lag-time (T-lag, AZD4721 only), dose-normalized AUC (AUC/D) and Cmax (Cmax/D)

    Measured: Sample taken predose, 1, 3, 5, 7, 9, 13, 18, 24, 36, 48, 72, 96, 144, 216 hours postdose

  5. Description of the pharmacokinetic(PK) profile for in terms of effective half-life (t½(eff)), time of last quantifiable concentration (tlast), predicted accumulation ratio (Rac,pred)

    Measured: Sample taken predose, 1, 3, 5, 7, 9, 13, 18, 24, 36, 48, 72, 96, 144, 216 hours postdose

  6. Description of the pharmacokinetic(PK) profile for in terms of the time interval and number of data points included in the log-linear regression to determine terminal half-life (z,Interval and z,N)

    Measured: Sample taken predose, 1, 3, 5, 7, 9, 13, 18, 24, 36, 48, 72, 96, 144, 216 hours postdose

  7. Description of the pharmacokinetic(PK) profile for in terms of the regression coefficient for calculation of the terminal rate constant (Rsq), and the percentage of area under the curve to infinity obtained by extrapolation (%AUCex).

    Measured: Sample taken predose, 1, 3, 5, 7, 9, 13, 18, 24, 36, 48, 72, 96, 144, 216 hours postdose

  8. Description of the pharmacokinetic(PK) profile for in terms of the metabolic ratios (ratio of metabolite to parent) for AUC and Cmax (MRAUC and MRCmax)

    Measured: Sample taken predose, 1, 3, 5, 7, 9, 13, 18, 24, 36, 48, 72, 96, 144, 216 hours postdose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AZD4721 Solution and AZD4721 Suspension in people with Safety,Plasma AUC and Cmax, Plasma AUC 0-t, t1/2λz, and Tmax, run by AstraZeneca at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Description of the safety profile in terms of Adverse events; blood pressure, heart rate and body temperature; electrocardiograms; clinical chemistry; haematology assessments, including serial blood neutrophil count (time frame: From Screening to follow up ( maximum 7 weeks)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jun 2015; AzTrials last refreshed its copy on 8 Nov 2026.
